You're right, in the right system he's a great 3rd liner. He isn't a top 6 player on a good team, but a great 3rd liner. But for those of you thinking he'll pot 20-30 on the 3rd line, that's wishful thinking. It's about ice time, he won't score 20 playing with those guys with 3rd line mins and no PP time.
Zibby and Conacher are both pretty skilled, and are coming into their own. Paul Mac doesn't really do lines, he'll play whoever is playing well that game. The fourth line could get the most minutes of they're scoring.
I actually think most coaches work that was these days.
